Letters Patent No. 114,413, dated May 2, 1871.

IMPROVEMENT IN HORSESHOE-NAIL MACHINES.

The Schedule referred to ln these Letters fatent and making part of thename.

To all whom. it may concern:

Be it known that we, HARLEY DWIGHT Oownns and GEORGE STACY, both of thecity of Montreal, in the district of Montreal, in the Province ofQuebec, in the Dominion of Canada, manufacturers, have invented new anduseful Improvements on the fManuf'acture of Steel Horseshoe-N ails andon the Apparatus used therein, and we do hereby declare that thefollowing is a full, clear,.and exact description of the constructionand operation of the same, reference being bad to the annexed drawing,where- Figure I represents a front elevation of a nail-cutting machine.

Figure 11 represents a detail plan of die.

Figure III represents a detail plan of punches and holders.

Figure IV represents three detail views of punches.

Figure V represents a side elevation of the punches and holders.

Figure VI represents a perspective view of the die in parts.

Figure VII represents a perspective view of the punches and holders inparts.

a This invention relates to that class of machines which is employed forpunching nails from previouslyrolled plates, and consists in certaindetails of construction, as will be fully described hereinafter.

. In the drawing similar letters of reference indicate like parts.

Letter (1, is the frame of the press or machine, made of cast-iron andof a size commensurate with the scale of the machinery required.

It is supported on legs l) l), and serves to hold the various parts ofthe machinery in proper position.

c is a pulley placed on the end'of shaft d, and communicates motion tothe same.

The shaft (l carries the eccentric, situated at e, which actnatcs thepitman c for the purpose of elevating or depressing the gate 0 moving inguides 0 attached to the framework 0.

In the lower part 'of this gate are placed the punches e in a shoe, e",fitting into a slot arranged in the gate,

and held in place by keys e.

These punches are held in place or supported by holders f boltedtogether, as shown in Fig. III, representing a bottom vie-W, with sideview in Fig. V.

As above referred to two punches are arranged to.

work at the same time, but when it is desired to use the machine withone punch, 2, only, the parts f and g are formed, as shown in FiguresXIII and XIV, for holding but one punch, and are secured in the press ormachine in a similar manner to that described as above for two punches.

g is a cast-iron bed bolted to the frame a, and provided with an openingthrough its center by which the nails pass after being cut.

On'the upper side of this block is a dovetail recess for the receptionof the dies g, held firmly in place by key g These dies are shown inplace in Figs. I and II, and in perspective in Fig. VI.

The configuration of the head of nail in the dies may he graduated byguides, so as to produce any desired length of head.

The operation is as follows The steel having first been rolled bysuitable machinery into strips of convenient length of the proper form,the latter are then introduced from the side of the machine between thecutters e and dies g, and fed forward automatically in proportion to thecutting power or velocity of the machine, the nail of steel beingdelivered in a finished condition by this one operation, through theaperture in blank g into a suitable receptacle below. g

Having now described our invention, to which we have given the name ofthe international steel horseshoe-nail, and the manner in which the sameis manufactured, we beg to state that we disclaim all other modes'ofmaking horseshoe-nails now in use.

\Vhat we claim as our invention, and wish secured by Letters Patent, is-

The apparatus in its novel combination of frame a, legs I), shaft (I,eccentric e, pitman e gate 0, guides e, punch or punches a, shoe 0*,keys e holders f, bed g, dies Q, key g, all working togethersubstantially in the manner and for the purpose described.

Montreal, 16th day of September, 1870.
